Brief Summary

This study is a prospective, single arm, single center exploratory clinical research, to evaluate KN035 late treatment in patients with Multiple Primary tumors (MPC, Multiple Primary working) clinical benefit.In the study, all subjects meeting the criteria for inclusion will be enrolled in the KN035 treatment group, and patients cannot receive any other anti-tumor treatment during the study period.The primary endpoint of the study was defined as patients who could be assessed by imaging, and the optimal Objective Response Rate (ORR) based on RECIST 1.1 standard, while the secondary endpoint was safety (nci-ctcae 4.0), DCR (Disease Control Rate), DoR (Duration of Response), progression-free survival (PFS),1) Overall Survival and Overall Survival;The end point of the exploratory study was the correlation between different molecular types and the efficacy of immunotherapy.

Eligibility Criteria

• Age: 18 Years - 70 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male or female, aged 18 or above, 70 or below;
• Patients with multiple primary tumors (currently suffering from colorectal cancer) diagnosed by histopathology (diagnostic criteria: ①the diagnosis of each malignant tumor must be confirmed by tissue/cytology;
• ②the pathological diagnosis of each malignant tumor has its unique pathological morphological support, different from other diagnoses;
• ③each malignant tumor diagnosis of the original site occurred in different parts, any two diagnosis is not mutually continuous;
• ④one of the diagnosis must be primary bowel cancer; (except for bowel cancer, other tumors do not need anti-tumor treatment);
• Currently suffering from intestinal cancer and distant metastasis;
• Received second-line or above treatment before, and the disease progress was determined by imaging; Or unable to tolerate any line treatment (including adjuvant or first-line treatment, etc., first-line treatment requires oxaliplatin, irinotecan and fluorouracil drugs);
• At least one measurable lesion (RECIST 1.1);
• ECOG score 0 or 1;
• Expected survival≥12 weeks;
• Adequate organ and bone marrow function (no hematopoietic growth factor, blood transfusion or platelet therapy was given within 1 week prior to the first study) :
• (1) blood routine examination: leukocyte ≥3.0 ×109/L, neutrophil ≥1.5 ×109/L, platelet ≥75 ×109/L, hemoglobin ≥ 9.0g /dL; (2) liver function: total bilirubin ≤1.5 ×ULN; ALT/AST≤2.5 ×ULN without liver metastasis; ALT/AST≤5 ×ULN in liver metastasis; (3) renal function: serum creatinine≥1.5 x ULN; (4) adequate cardiac function, left ventricular ejection fraction (LVEF) \> 50% of 2-d echocardiography.
• \. Fully understand the study and sign informed consent voluntarily; 10. Women of reproductive age who have had a negative pregnancy test are willing to take effective contraceptive measures during the study period and within 90 days after the last dose of medication.

You may not qualify if:

• Participate in clinical trials of other research drugs within 30 days before the first study drug treatment;Or received anti-tumor therapy within 2 weeks, including but not limited to chemotherapy, radiotherapy, targeted therapy, or anti-tumor therapy, the toxic response has not returned to the level 0 or level 1 (hair loss, ≤grade 2 peripheral neurotoxicity induced by chemotherapy can be included);
• Previous immune checkpoint drug therapy;
• Major surgery (except biopsy) or incomplete incision healing was performed within 4 weeks before the first study of drug therapy;
• Ascites requiring drainage or diuretic treatment or hydrothorax or pericardial effusion requiring drainage and/or symptoms of shortness of breath within 2 weeks before the first study;
• Active brain metastasis or spinal cord compression;For patients with brain metastasis who had received previous treatment, if the clinical conditions were stable within 4 weeks before the first study of drug treatment and the imaging evidence did not show the disease progression, and if they did not need corticosteroid treatment within 2 weeks before the first treatment, they could be considered to be enrolled.
• Active, known or suspected autoimmune diseases (patients with vitiligo who do not require systematic treatment within 2 years before the first study of drug therapy are allowed to be enrolled;Patients with hypothyroidism requiring only thyroid hormone replacement therapy, type 1 diabetes requiring only insulin replacement therapy, and patients with pituitary inflammation and adrenocortical dysfunction requiring only physiological hormone replacement therapy can be enrolled);
• Hiv-infected patients;
• An active bacterial or fungal infection requiring systematic treatment 14 days before the first study drug treatment;
• Previous history of interstitial lung disease, drug-induced interstitial lung disease, radioactive pneumonia, symptomatic interstitial lung disease, or any evidence of active pneumonia on chest CT scan within 4 weeks prior to initial study drug treatment;
• HBV DNA≥2000 IU/ml (or 104 copies /ml) during screening period in patients with hepatitis b; Note: for enrolled subjects with anti-hbc (+)/HBsAg (+)/HBV DNA\<2000 IU/ml or anti-hbc (+)/HBsAg (-)/HBV DNA\<2000 IU/ml, antiviral therapy must be provided at the same time during the trial, either with the original drug or entecavir.For enrolled HCV rna-positive subjects, it was up to the investigator to decide whether to also receive antiviral therapy.
• Clinically significant cardiovascular diseases, including but not limited to acute myocardial infarction, severe/unstable angina, cerebrovascular accident or transient ischemic attack, and congestive heart failure within the first 6 months of enrollment (New York heart association grade ≥ 2);Arrhythmias that require other antiarrhythmic drugs in addition to beta blockers or digoxin;Repeated electrocardiogram (ecg) detection of QTcF interval of \>450 milliseconds (ms);Hypertension not well controlled by antihypertensive drugs (systolic blood pressure \>150mmHg, diastolic blood pressure \>100mmHg);
• Abnormal thyroid function exists, and the use of drugs cannot maintain thyroid function in the normal range;
• Clinically significant abnormal serum electrolyte level;
• Immunosuppressive drugs were used within 2 weeks before the first study drug treatment, excluding local or systemic glucocorticoids not exceeding 10 mg/ d prednisone or other glucocorticoids of equivalent dose;
• Live vaccine should be administered within 4 weeks before or during the first study period of drug therapy.
